Abstract

This reserach aims to analyze and provide recommendations for improving the effectiveness of the internal control system in inventory management at PT TMT. PT TMT is a medium-sized manufacturing company specializing in elevators and escalators, where inventory serves as the main source of revenue for the company. Having a good internal control is crucial to influence PT TMT's business operations and mitigate existing risks. However, as a medium-sized company, PT TMT faces limitations in resources, infrastructure, and income, which can hinder the implementation of an effective internal control system. This research adopts a qualitative approach that refers to the COSO framework. Data collection techniques include interviews, direct observations, and analysis of PT TMT's Standard Operating Procedures (SOP) documents. Based on the research findings, it was found that PT TMT still has weaknesses in internal control related to the five components of the COSO internal control framework. This study is expected to provide accurate information regarding the internal control condition at PT TMT and offer recommendations to improve the weaknesses in the company's internal control.

Abstract

Effective inventory management is crucial in the distribution industry, as inventory levels and conditions directly affect the overall efficiency, continuity, and effectiveness of an organization's activities. This study aims to critically explore the implementation of internal control over the inventory cycle at PT. XYZ, a multinational distribution company, uses the Internal Control–Integrated Framework of the Committee of Sponsoring Organizations of the Treadway Commission (COSO). This research is motivated by the findings of an internal audit conducted in 2023, which identified several areas that need improvement, including stock shortages, management of obsolete goods, loss of inventory, and recording mismatches. Through a qualitative case study approach, this study examines the extent to which a company's internal control practices are in line with the five core components of COSO: control environment, risk assessment, control activities, information and communication, and monitoring. The results show that although internal control mechanisms have been implemented, improvements are still needed, especially in the implementation of separation of duties, automation of the inventory recording process, and strengthening the control environment through better company policies. This study provides strategic recommendations to strengthen the internal control framework at PT. XYZ as well as providing relevant insights for other entities in the distribution sector that want to optimize inventory control systems and mitigate operational risks.

Abstract

Abstract: Plates are a very important part of shipbuilding and offshore structures. The reinforced plate is used to withstand loads acting in the axial and bending directions. The structure of the deck or bottom plate exhibits buckling or yielding behavior. Thus, it is very important to analyze the ultimate bearing capacity of a plate structure subjected to compressive loads for safe ship structure design. The material configuration used is the most important aspect in the FPSO structure design criteria. Plates and stiffened plates experience local buckling due to the external load when the hull girder collapsed. The objective of the present study is to analyze the effect of flange and web thickness to the ultimate strength on the FPSO in terms of plate deformation located of the bottom and deck area under compression stages. In this study, the attached plate thickness is varied according to FPSO data and BKI Rule. The stiffened plates element located at the bottom and deck area are modelled by Tee-Bar and Angle-Bar element. The simply supported condition is applied to the model and the anon-liniear Finite Element Method is used for the analysis. The result obtained by NLFEM shows that under tension and compression, the stiffened plate of Tee-Bar model, the deformations are 1,75 mm and 1,8 mm respectively. While for Angle-Bar model the deformation are 12,4 mm and 13 mm under compressing respectively.

Abstract

Performance allowance is a right for every civil servant which is calculated based on employee performance achievements. Performance allowances are included in employee expenditure which ranks third largest in the State Revenue and Expenditure Budget after capital and goods expenditure. The types and procedures for paying performance allowances are very complex, such as master, follow-up, continuous, shortage, 13th month, and THR performance allowances with different calculation formulas according to the grading order, in addition to the number of work units as many as 9,104 for all State Ministries/Institutions with a total of 967,724 employees, the development of a reliable and adequate information system is needed. The Directorate General of Treasury already has a performance allowance module on the web salary application, but it still needs to be improved and refined so that the process of recording, calculating, testing, and disbursing the process is easy and safe. The application design is not only from the side of the work unit but also from the side of KPPN. The research will use the segregation of duties method to map the separation of functions in terms of making and testing performance allowances, while for application design, Famework for The Application of System Thinking (FAST) will be used, especially for the initial four stages, namely scope definition, problem analysis, requirement analysis, and logical design with various uses of diagrams such as business process diagrams, use case diagrams, Flowchart, Data Flow Diagram, Entity Relationship Diagram is to describe the needs, planning of activities, ease and direction in system development.

Abstract

This study examines the comparative investment performance of Bitcoin and gold during the COVID-19 recovery period from March 2020 to December 2024. Using daily price data, the research employs Return on Investment analysis and ARCH- GARCH volatility modelling to assess the risk-return characteristics of both investment instruments during this critical economic period. The analysis reveals fundamental differences between the assets. Bitcoin exhibited average daily returns of 0.18% compared to gold's 0.04%, while demonstrating volatility 3.10 times higher than gold. ARCH-GARCH modelling confirms distinct volatility dynamics, with Bitcoin showing high volatility persistence indicating clustering effects, while gold demonstrates minimal persistence with no GARCH effects, reflecting stable characteristics. Five research hypotheses were tested and supported. Bitcoin demonstrated superior ROI performance but with substantially higher volatility than gold. GARCH models provided superior fit compared to ARCH specifications for both assets. The analysis reveals significantly different risk-return profiles, positioning Bitcoin as a high-risk, high-return asset suitable for risk-tolerant investors, while gold maintains its role as a stable portfolio diversifier. The findings demonstrate that Bitcoin and gold serve complementary rather than competing roles in investment portfolios during crisis periods. The results provide quantitative evidence for investment decision-making between traditional and digital assets, contributing valuable insights to cryptocurrency investment literature during unprecedented market conditions.

Abstract

Indonesia is the world’s largest producer of crude palm oil (CPO). By 2024, national CPO production and stocks were projected to exceed 57 million tonnes,  allocations for exports of 29.5 million tonnes, biodiesel production of 12 million tonnes, and domestic food consumption of 11.1 million tonnes. This study aimed to analyze the investment feasibility of PT X’s 300-hectare oil palm plantation expansion in West Kalimantan using capital budgeting and scenario analysis. A qualitative descriptive single-case study design was employed using primary data obtained from management interviews and field observations, as well as secondary data from PT X’s internal financial model, Bappebti CPO data, Bank Indonesia government securities (Surat Berharga Negara/SBN) yield data, and Damodaran financial data. Eight financial evaluation methods were applied: Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), Discounted Payback Period (DPP), Profitability Index (PI), Cost of Debt, Capital Asset Pricing Model (CAPM), and Weighted Average Cost of Capital (WACC). All feasibility indicators demonstrated positive results, with an NPV of IDR 23.978 billion at a 12% discount rate and IDR 20.459 billion based on WACC of 13.16%; an IRR of 26.78%; a PP of 6.95 years; a DPP of 8.46 years; and a PI of 3.33. Scenario analysis across six land-price variations (IDR 15–34 million/hectare) confirmed investment feasibility under all scenarios, with IRR values ranging from 26.78% to 39.56%. The IRR–WACC spread of 13.62 percentage points indicated significant economic value creation, with an estimated Economic Value Added (EVA) of IDR 4.68 billion per year.

Abstract

This study aims to analyze the business processes and design a Microsoft Excel based accounting information system for Family Optic. Currently, transaction recording at Family Optic is conducted manually using handwritten records, resulting in unstructured transaction documentation, limited inventory monitoring, and revenue estimates based on assumptions. To address these issues, this study designs an accounting information system for the revenue and expenditure cycles. This study employs the System Development Life Cycle (SDLC) method and incorporates the threats and controls framework to identify risks and determine appropriate controls for both cycles. The proposed Excel based accounting information system was tested through transaction simulation only. Therefore, scope of this study is limited to system design and simulation based testing. Full implementation and operational use were beyond its scope. The resulting system integrates a chart of accounts, inventory master data, purchase and sales records, cash receipts and cash disbursements records, journals, and income statements. The design system supports more systematic transaction recording, enables perpetual inventory monitoring, and generates more  structured financial information to facilitate business decision making.
